If sperm cells are absent in the semen in men (azoospermia), children cannot be conceived naturally. The unfulfilled desire to have children can be the cause of a high level of suffering among the couples concerned. The unfulfilled desire to have children can also put a strain on the relationship.

​

The extraction of sperm cells directly from the testicular tissue by a surgery (TESE) is often the only way for men with azoospermia to become a biological father. The sperm from the testicular tissue can be used for artificial fertilization (ICSI).

​

The probability of finding sperm in the testicles of men with azoospermia can be increased if the surgery is performed under an surgical microscope (micro-TESE). Often sperm formation and maturation (spermatogenesis) is unevenly distributed over the testicles, especially in the presence of azoospermia. With the conventional TESE, the tissue is randomly removed from the testicle somewhere. The micro-TESE offers the special possibility of determining and extracting areas in the testicular tissue with a higher probability of finding sperm at up to 20-fold magnification. Many scientific studies have shown that the micro-TESE has a higher sperm finding rate than the conventional TESE.

In the European guidelines of urology (EAU-Guidelines) and the US-American guidelines of reproductive medicine (ASRM-Guidelines), micro-TESE is evaluated as the most promising surgical treatment for azoospermia due to a sperm formation disorder in the testicles (non-obstructive azoospermia).

We perform the micro-TESE under the most modern Leica Provido surgical microscope, which was recently released in 2019. The most modern optics, the Xenon and LED lighting expand the possibilities of intraoperative visibility.
